SPECIFICATION forming part of Letters Patent No. 650,002, dated May 22, 1900.

I Application filed February 16, 1900. Serial No. 5,515. (No model.)

To all whom it may concern! Be it known that I, JAMES W. H. BRADLEY, a citizen of the United States, residing at Magnolia, inthe couut'yof Columbia and State of. Arkansas, have invented certain new and 1186-. ful Improvements in Cotton Choppers, of which the following is a specification.

Myinvention is a cotton-chopper, and is designed to thin the cotton out of the rows to the proper stand.

In the accompanying drawings, Figure 1 is a side elevation of my invention. Fig. 2 is a top plan View. Fig. 3 is a bottom plan view. Fig. 4 is a detail of part of one of the axles, hub, adjustable arms, knives, and hoes. Fig. 5"is an edge view of the double central hearing. Fig. 6 is a face view of the same.

My invention consists of two longitudinal beams 1 and 2, secured together by a front cross-beam 3, central cross-beam 4, rear crossbeam 5, and a front rod 6. Secured to the lower edges on each end of the beams 1 and 2 and extending downwardly are four beams 7, 8, 9, and 10. Secured in the lower ends of each of these beams are bearings 11, and j on r naled in these bearings are axles 12. Secured to each end of these axles are'wheels 13. The periphery of these wheels are rounded, that shape causing them to run more evenly in the middle between the cotton-rows.

To the inner face of the right-hand front wheel is rigidly secured a cog-wheel14, its cogs extending inwardly from its inner face.

Secured to and extending downwardly from the forward cross-beam 3 is a bearing 15, and secured to and extending from the rear crosspiece 5'is another bearing 16, and secured to and extending from the middle cross-beam 4 is a double bearing 17. (See Figs. 5 and 6.) This bearing consists of two downwardly-extending arms 18, integral with a bow 19, and extending from one side and the front face of said bow is an arm 20, having in one edge a depression 21, forming one-half of a socket for the end of an axle, hereinafter mentioned, to work in. This one-half socket is supplemented by a bracket 22, having a like onehalf socket, which is bolted to the edge of the arm 20. Extending from the other side of the bow and from the rear face thereof is another arm 23, having in oneedge a depression 24, forming one-half of a socket for the end of an axle, hereinafter mentioned, to work in. This one-half socket is supplemented by a bracket 25, having a like one-half socket which is bolted to the edge of the ar1n 23.

J ournaled in the bearing 15 and in the depression21 of the arm 17 is an axle 26, and rigidly secured to the forward end of said axle is a cog-pinion 27, meshing with the cogs of cog-wheel 14, and near the rear end of this axle is rigidly secured a hub 28, having extending from the periphery thereof three slotted arms 29. These arms are each'provided with a double slot-a wide slot 30 on one side and a narrowslot 31011 the other side. (See Fig. 4.) Arms 32 fit the wide slots 30 and are adapted to work longitudinally therein and against the back wall of said slots 30. Headed bolts 33 pass through said arms 32 and through the narrow slots 31 in arms 29,

and a nut 34 works on-the threaded end of i said bolt and is adapted to be loosened or tightened, and thus said arms 32 are made longitudinally adjustable in relation to the arms 29, and to the outward end of each of these arms 32 is secured a hoe;35. l

On the rear end of the axle 26 is rigidly secured a cog-pinion 36. An axle 37 has its rear end journaled in bearing 16 and its front end journaled in depression 24 of arm 23 of the double bearing 17, and on the forward end of this axle is journaled a cog-pinion38, which meshes with cog-pinion 36. On said axle 37 is rigidly secured a hub 39, and ,to said hub 39 are secured hoes 4O exactly in the same manner and having the same adjustable means as hoes 35 are secured to hub 28.

To the front end of the frame and to the rod 6 is secured a pair of hounds 41 to attach the team to, and to the top and rear end of the frame are secured in the ordinary way a pair of handles 42.

As the cotton-chopper is moved forward the cog-wheel 14, meshing with the pinion 27, revolves the front hoes 35 to the left. The pinion 36, meshing with the pinion 38, revolves the rear hoes 40 to the right.

The gearing is so constructed that two hoes-one 35 and the other 40--pass over the top of the row of cotton exactly at the same moment of time, and as the hoe which revolves from the left tends to throw the uncut cottonstalks to the right, the hoes revolving to the right would at thesame time tend to throw the uncut stalks ;to-.-:the left, and thus the young cotton will be kept standing upright,

and thegearing of the machine is so arranged I frame, consisting of two side beams land 2; three cross-beams 3, 4 and 5; bearings '7, 8, 9 and 10' extending downwardly from each that the hoes strike the rows of cotton at" such distance apart from eachlick to leave between each cutoneor more stalks ofcotton. I

V v .The object of using the double bearing and the brackets 22 and 25 is to the end .that the brackets may be removed and the gearing conveniently taken out, cleaned repaired, or replaced.

Having described my invention, what I claim as new, and desire to secure by Letters:
